Design a Security Monitoring Framework
Company: Google
Role: Software Engineer
Category: System Design
Difficulty: medium
Interview Round: Technical Screen
Design a security monitoring framework for a cloud infrastructure environment.
The framework should monitor hosts and workloads for suspicious behavior, detect potential attacks, and deliver useful security signals to downstream systems or security analysts. The interviewer may ask for low-level details such as how attacks can be observed from the operating system, how eBPF can be used for monitoring, and how shared buffers can transfer events from kernel space to user space.
Discuss requirements, architecture, event collection, attack detection, data flow, performance, reliability, privacy, and operational tradeoffs.
Quick Answer: This question evaluates a candidate's understanding of designing security monitoring frameworks for cloud infrastructure, covering competencies in system architecture, OS-level observability (including kernel-to-user event transfer and eBPF), event collection and attack detection, and considerations of performance, reliability, and privacy.
